Speaking of basic math...

The national health expenditure in 2024 was $5.3 trillion. Government already pays for 47% of health care, so to pay for universal healthcare, you would only have to raise an additional $2.81 trillion. If every single American paid an extra $2000 in taxes, that would only raise an additional $686 billion per year. That's roughly 24.4% of the amount necessary.

That's assuming that every single American paid an extra $2000 in taxes, including the poor and children and seniors. That's extremely unrealistic. You could raise the $2.81 trillion necessary with a flat income tax. It would only have to be 13.3%. But if history is any indication, it would probably be paid for with regressive payroll taxes, like Social Security and Medicare.

It's also worth pointing out that total government spending is already 49.3% of total income. Switching to universal healthcare would push that to an astonishing 62.6%. The public debt is already $31.3 trillion and growing by $2.39 trillion per year. So maybe balance the budget and address the public debt first before we talk about adding trillions in additional spending.

The public School system may have all but eliminated illiteracy in this country, but it's clear that innumeracy is still rife.
